I had a leak that only showed as a small bubble under water, that would re-form if I brushed it away. Can be darned hard to find sometimes, if the tube had been facing the other way underwater I wouldn't have seen it. Just the tiniest pinprick, but it went flat overnight.
Oh - and IF you use tubes with Presta valves in rims with a hole big enough for the other valves (Schraeder? summat like that) you need a little plastic liner thingy in the hole first or the tube will squeeze in there and get a pinch flat first chance it gets. BTDT.
